Be it known that I, JOSEP Moms, a citizen of the United States of America, re-

. siding at Nashua, inthe county of Hillsborough and State-of New Hampshire, have invented'iiew and useful Improvements in. Stamping Machines, of Which the following is a specification.

This invention relates to numbering na- -c'hines and more particularly to a type of .machine adapted forhand operation to apply selective numbers to boxes, or any con tainers or other surfaces. all respects limited thereto the nvention is preferablyand as herein shown 'embodied t mechanism for operating the signalbell;

- in a type of stamping machine wherein the combinations of numbers. One principal ob- I numbers are borne by series of rubber bands.

which are adjustable to present the required ject of the invention is to provide a number.-

ing machine-of the type stated with an automatic counteror registering device adapted to register accurately the number of times that any given number has been stamped. A

further object is to providea combination numbering and registering machine of the type SGtVfOIth j with a bell or likersignal adapted to indicate by its ring each impression made by the stamping machine.- A further object is to provide a numbering machine with a printing face equipped with fingers or feelers adapted when pressed against the "surface to be printed, to cause the actuation of the registering counter and also to operate the bell or like signal. A still further object is 'toprovide improved means for adjusting the'rubber bands which v bear the numbers, the device for this; purpose embodying also a locking clamp holding the numbers from movement while being used. A still further object is to provide a Ynumbering machine with a convenient compapa ' the invention will more fully appear frompartment for holding a reserve stock of ink. A'still further object is to provide a numbering machine of the type-stated that is economical of time and labor in use and ble of insuring both speed and accuracy without any particular skill on the part of thei operator in using'the same. The foregoing and other objects andadvantages of the following detailed description taken in connection with the accompanying drawand the distinctive' features ofnovelty. flwillbe pointed out in the 'appendedclaims.

cess to this. chamber one end thereof may be closed by a detachable plug 13 having a The rubber bands which four in number with a a designation 414. These bands are mounted at their upperportions upon rolls or drums 15, the surfaces of which may be suitably roughened to obtain a proper frictional holdvupon the bands for turning the same. The lower portions of around a plate16 fixed to the bottomsjof the side plates 10", 11. The drums 15 are rotatively mounted upon a shaft 17 which extends across the frame with its ends mounted in slots 18 ofthe plates 10,,11.,As shown these slots areof' a keyhole type with a relatively reduced upperportion18 in which the ends of the shaft 17' arenormally received, the shaft ends having notches engaging the sides ofthe slots toprevent dicated at .18 to permit removal of .the shaft endwise when'it is located in this part of the slots. For moving the shaft 17 upendwise removal, while the j lower portions .of the slots are relatively enlarged as-inwarfdin the slots 18. which results in draw- 1 I ingithe bands 1 f taut and preventing-turne mg thereof; this shaft is engaged the sides; of; horizontal slots 192. a swinging I swung outward on its pivots resulting in lowering the slots 19 and hence the shaft 17 to loosen the rubber bands and permit them to be turned, Suitable means may be prov ded or ec'king th swing g frame in its inward position with the bands held taut and against movement. For this purpose I show spring pressed pins 23 fitted in housings 24 borne/by the side plates 10, 11, these pins being pressed into holes 25 of the swinging frame when said frame is swung inward as shown in Figure 2. These pins are equipped with compression springs 23 enclosed in the housings 24 and have at their projecting ends finger pieces 23 by which they may be drawn outward. For turning the drums 15, each of them bears a ratchet wheel 26 upon its huh portion and these ratchet wheels are engaged by spring pressed pawls 27 pivoted to lever plates 28 swingingly mounted upon the shaft 17. These plates are equipped with projecting finger pieces 28- .a t the upper edges thereof and their lower edges are also formed with projections 28 engageable with a shaft 29 borne by the frame which limits the downward or return movement of said levers. Thus by operating the finger pieces 28, any required combination of numbers may be presented in operative position, i. e. underneath the plate 16. 30 indicates a pad holder for an inking pad 30*, which is mounted to swing into position for applying ink to the numbers after each operative movement. For this purpose the pad holder bears at its ends bent upturned arms 31. The upper ends of these arms are fixed to a shaft 32 which extends across the frame and has its end portions pivotally mounted in swinging bars 33 at the sides of the frame, the inner ends of these'bars being'fixed to the extremities of theshaft 29. An intermediate portion of the shaft 32 has fixed thereto short spaced apa it arms 34, the outer extremities of which are pivotally engaged at with th lower end of an upwardly extending bar 36. The

39 which is journalled on a shaft 40 extending across the upper portion of the frame. The lever 39 is formed with an outwardly projecting finger piece 41 which may be of substantial width, i. ,e. extending substantially across the frame so that all of the fingers of the hand may engage therewith. One important feature of the invention comprises means whereby a counter is operated and a signal, such as a bell actuated at each stamping impression made by the machine. For this purpose I provide spaced apart fingers or feelers 42 slidably mounted to extend in one position downward below the stamping plane, and being pressed backward when the impression is taken, this pressing backward of said fingers serving to actuate the counter and the bell. As herein shown the fingers 42 are united together by a plate 43 and they are slidably guided for vertical movement. having slots 44 in their upper ends which fit around a shaft 45 journalled in the slide plates. unit has secured thereto a bar 46 extending upwardly in the frame with its upper end pivotally engaged at 47 with a short lever arm 48 fixed to the shaft 40, This shaft 40 extends at opposite sides of the frame with its extension at one side having a counter device 49 associated therewith to be operated by a one-way movement of the shaft 40 to register the stamping operations. Theother end portion of the shaft after extending through a sleeve bearing 50 within the frame. projects outward through the side plate 10 where it has fixed thereto an arm 51 bearing a pivoted pawl 52. This pawl on the reverse clockwise. movement of the shaft 40, as seen in Figure 6, i. e. as the fingers 42 are being pressed inward, engages a shoulder 53 on a head 54 pivoted on a stub shaft 55 at the end of the frame. This head 54 bears an arm 56 with a bell hammer 57 at its outer end and it is acted on by a spring 58 mounted on the shaft 55 which normally tends to swing the hammer 57 into engagement with a bell 59. Thus the pawl 52 engaging the shoulder 53 draws the bell hammer inward as the fingers 42 are being pressed inward for a stamping operation, and as soon as such operation is completed, the pawl 52 passes the end of the shoulder 53 permitting the reaction of the spring 58 to sound the bell, while the pivotal mounting of the pawl 52 permits it to ride past the shoulder 53 on the return, or resetting movement of the fingers 42. This resetting movement of the fingers 42 is accomplished by a spring 60 mounted on a fixed shaft or bar 61 in the lower portion of the frame with projecting extremities 60 60 engaging" in holes 42 in the fingers 42. Suitable means is provided for holding the fingers 42 retracted after an operating movement until after the inkingpad has been pressed upon This feeler or fingerthe stamping surface. For this purpose one of these fingers'is provided with a small block 62 presenting a ledge-or shoulder 62. for co-operation. with a part circular stop or abutment member 63 formed upon the shaft 45. This abutment member 63 is cut away at one side thereof as indicated at 63 at a point so that when the shaft is oscillated as now to be described in withdrawing the inking pad from the stamping surface, this cut away portion will come opposite the ledge 62 and permit the fingers to be pressed downward by the action of the spring 60. This oscillation of the shaft 45 is accomplished by means of a pivoted pawl 64 mounted on a head 65 borne by the shaft 29, this pawl engaging a ledge 66 on a head 66 fixed to the shaft 45. The pawl 64 is adapted to move past the shoulder 66 on its operating movement, and after releasing the fingers 42 as described, the shaft 45 is returned or reset by means of a spring 67 engaging the same. For returning the parts including the inking pad and the hand piece to normal position, i. e. with the stamping pad pressed upon the stamping surface, suitable spring means is provided, this being shown as a stout coil spring 68 mounted upon the shaft 29 with one end thereof fixedly anchored asindicated at 68, and its other end engaging a short arm projecting from the shaft as indicated at 68 Thus at the beginning of an operating movement the user taking hold of the finger piece 41 draws 1 the inking pad 3O away from the stamping surface, the fingers 42 being then projected beyond the stamping surface as shown in Figure 3. Then as the machine is pressed upon the material to stamp the desired impression, the fingers 42 will be pressed backward against the tension of the spring 60, this resulting in oscillating the shaft 40 through the link bar connection 46 until the completion of the operating movement, when as the fingers are fully pressed inward, the

awl 52 moving past the ledge 53 will permit th bell to sound, while at the same time the other end of the shaft 40 actuates the counter. Thereupon the operator releasing the piece 41, the inking pad is returned over the stamping surface by the spring 68, the fingers 42 being then held retracted by the engagement of the shoulder 62 with the stub or abutment member 63. Upon starting to draw back the inking pad the shaft 45 is oscillated as described to release the shoulder 62 and permit the fingers to be again embodied in other specific forms without tributes thereof, and I therefore desire the a present embodiment to be considered in all respects as illustrative and not restrictive, reference being had to the appended claims rather than to the foregoing description to indicat the scope of the invention.

I-Iaving described my invention, what I claim as new and desire to secure by Letter Patent is:

1. The combination with a machine for stamping numbers or the like having stamping elements, of registering'and signal mechanism associated therewith having an operating element projecting normally beyond the printing face and yieldable as the'printing face is pressed upon a receiving surface, to actuate said registering and signal mechamsm.

2. A numbering or like machine comprising adjustable bandspresenting a printing face, registering and signal mechanism, fingers yieldably mounted and normally projecting outward from the printing face having a connection to actuate said registering and signal mechanism as they are pressed inward by engagement with the receiving surface, and means for inking the printing face while said fingers are withdrawn.

. 3. A portable hand operated machine for numbering and like uses comprising a printmg face, registering and signal mechanism, I

locking the same against movement after 1 adjustment thereof.

5. A stamping machine comprising a plurality of bands presenting a changeable printing face, a ratchet device for each of said bands to actuate the same, and a swinging mountin for the bands adjustable to loosen them or movement and to hold them taut against movement for operation.

In testimony whereof I afiix my signature.
